Generation of the first PALSAR-2 global mosaic 2014/2015 and change detection between 2007 and 2015 using the PALSAR and PALSAR-2

摘要

Decreasing the carbon emission from the deforestation and forest degradation is one of the issues that the humans need to tag for sustaining the Earth. Monitoring the forest from the space is the recent achievements that the space agencies contribute. Measuring the forest cover change is being conducted by using the high resolution optical and/or SAR images. ALOS-2 has been on-orbit carrying the L-band SAR since May 24, 2014. After more than one year data acquisition and related processing, the first version of the 25-m resolution global PALSAR-2 mosaic dataset from the 2014-2015 acquisitions, forest-non-forest map, and the forest cover change from 2007 to 2015 were generated.
